Abstract

A damper device for a spring suspension for a bicycle wheel comprises a fluid-cylinder unit, which is delimited into two chambers (91, 92) by a piston (94). A tubular valve body (31) is coaxially arranged inside a tubular longitudinal section (81) of the piston rod of the cylinder unit and is biased by a spring (35) in the direction upwards toward the piston (94) into an end position (33), wherein a valve cone (38) of the valve body closely screens off a wall opening (32) arranged in the piston rod and situated under the valve body, for the formation of an inertia-sensitive member (31, 35), which temporarily opens a fluid pipe (51) between the fluid chambers (91, 92) upon load from the wheel to the frame, but substantially blocks the fluid pipe in the opposite load direction.
